Folder Options Problems

I was messing around in my folder options, trying to change some icons under file types, while trying to change my icon file folder icon under advanced I seem to have some how screwed with the actions now the default action is find, and the only other option is scan with adware. So now when I right click on any folder, it goes to the search screen, I must left click on the folder and click on the open potion in order to open the folder. Does anyone know how I can simply recover from my stupidity?
